Note: Install the hearth extension only as illus-
trated.

The safety strips should extend from front of
the fireplace at least 1 

¹⁄₂

" and should extend to

be at least flush with the sides. In the event a
wooden support is used to elevate the fireplace
above the floor, a “Z” type safety strip should be
fabricated and used to protect the front surface
of the wood support as well as the floor beneath
the hearth extension (

Figures 8 and 9 ). The

safety strips should be tacked down to prevent
possible movement.

Note: The “Z” type safety strip is not supplied.

2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.

3. Note the floor construction, i.e. 2 x 6’s, 2 x 8’s
or 2 x 10’s, single or double joists, type and
thickness of floor boards.

4. Use this information and consult your local
building code to determine if you need addi-
tional support.

CAUTION: DO NOT BLOCK THE HEAT-CIRCU-
LATING AIR INLET AND OUTLET PORTS ON
CIRCULATING MODELS.  DOING SO MAY RE-
SULT IN A POTENTIAL FIRE HAZARD.

If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on top.
Secure the platform to the floor to prevent
possible shifting.

FIREPLACE CLEARANCES

Minimum clearance to combustibles for the
appliance is as follows: sides and back - 

¹⁄₂

" (13

mm), floor - 0" (0 mm), adjacent wall - 12" (305
mm), ceiling - 37 

¹⁄₂

" (953 mm).

INSTALLING THE FIREPLACE

Step 1. Slide the fireplace into prepared fram-
ing or position fireplace in its final position and
frame later.

The fireplace may not be recessed into a com-
bustible floor. Maintain the floor to hearth clear-
ance established by the fireplace lower front face.

Step 2. Insert the provided metal safety strips,
beneath the fireplace as illustrated (

Figures 6, 7

and 8 ). The safety strips should overlap 

¹⁄₂

" for

continual coverage of the floor.

Note: Safety strips are not required when fire-
place rests on a noncombustible surface.

ASSEMBLY STEPS

Note: The following steps represent the normal
sequence of installation. Each installation is
unique, however, and might require a different
sequence.

1. Position firebox prior to framing or into
prepared framing.

2. Install the chimney system.

3. Connect house wiring to the fireplace for
later attachment of optional blower.

4. Install optional outside combustion air kit.

5. Plumb gas line if a decorative gas appliance
will be used. (Gas connections should only be
performed by an experienced, licensed/certi-
fied tradesman.)

6. Complete the installation, finish wall mate-
rial, surround and hearth extension to your
individual taste.

7. Assemble and attach optional glass door
assembly.

Study the three dimensional illustration (

Fig-

ure 1 ) to get a general idea of each element of
your fireplace system.

PRE-INSTALLATION NOTES

The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, ply-
wood, particle board or other hard surfaces.
Be sure fireplace rests on a solid continuous
floor or platform with appropriate framing for
support and so that no cold air can enter the
room from under the fireplace.

The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.

Usually, no special floor support is needed for
the fireplace, however, to be certain:

1. Estimate the total weight of the fireplace
system including chimney and surround ma-
terials such as brick, stone, etc., to be in-
stalled.  Shipping weights for the fireplace may
be found on page 18.
